I have an EX4 with 4x 3TB WD Red’s in, its been running fine for years.
Yesterday I noticed 2 red lights on it and the screen says drives 1,3 has failed. I thought it very unlucky 2 drives would have failed at the same time but the MyCloud insisted that was the fault even after a couple of reboots.
So, today I replaced the drives with 2 new WD Red’s exactly the same model, powered down the system replaced the drives and powered it back up.
I was surprised to see the same fault displayed on the screen so i thought maybe it needs some intervention in the dashboard so i try to fire that up and after putting in my username and password it comes up with a screen that says please add a hard drive and click continue. I’ve done this multiple times and nothing changes, I’ve tried removing the drives so there are none in the failed bays 1 and 3 but still the same.
I then took all the drives out, moved them around done everything i could think of and on each power cycle i either get no drives installed when there are or i get ports 1,3 and one i even saw bay 2 is red.
I have also tried the 40 second reset which still does not resolve.
I’m thinking it might actually be the MyCloud itself now but id like to hear others thoughts.
